Call your ISP, they can tell you if your modem is supported, and they will need to allow it to connect. It will be possible if they allow it.

This is a common misunderstanding due to trying to think of things classically. I'd recommend "the road to reality" by Penrose if you want a better understanding.

Also it is not why we cannot use entanglement for FTL info, but you'll understand that more once you understand entanglement better.

Not paying attention to anything happening right now, are you?
